High power 1:1 current balun, coax to ladder line. Post 1704.

If you can't see the video, please insert this title URL into your browser search box:

Here's a gadget that could help protect your HF transceiver and perhaps even improve antenna performance.  Baluns, such as the one introduced in this excellent video, create a high impedance to common mode currents which flow on the outside of a coaxial cable shield.  In this video, the balun consists of 10 turns on two stacked FT-240-31 torroidal cores.  A handy, sturdy, and inexpensive way to make sure equal currents go into each arm of your dipole antenna.
